The examples of mine on Gleicon's site include working V4L greyscale capture with
the bttv (Bt848) driver.
Maybe the Creative webcam Plus hardware and/or driver doesn't support it.
If you just want greyscale data (as opposed to wanting it for lower datarates),
then just convert the RGB to YUV and use the Y - that's what the bttv greyscale
is. There are a zillion RGB-YUV conversion routines out there, including a
reasonably fast one in the tarball of mine on Gleicon's site.
